The Eocene is not only known for containing the warmest period during the Cenozoic; it also marked the decline into an icehouse climate and the rapid expansion of the Antarctic ice …

2012年8月1日 · This paper presents a record of terrestrial climate and vegetation dynamics on Antarctica that spans the peak greenhouse phase of extreme warmth during the early Eocene, …

The Eocene–Oligocene transition (EOT) was a climate shift from a largely ice-free greenhouse world to an icehouse climate, involving the first major glaciation of Antarctica and global …

2024年6月5日 · Our findings reveal the Eocene as a transition period from >40 million years of relative tectonic quiescence toward reactivation of the West Antarctic Rift System, coinciding …

Understanding the extreme greenhouse of the Eocene (56–34 Ma) is key to anticipating potential future conditions. While providing an end member towards a distant high-emission scenario, …

2016年3月10日 · About 34 million years ago, Earth’s climate cooled and an ice sheet formed on Antarctica as atmospheric carbon dioxide (CO 2) fell below ~750 parts per million (ppm). …

2004年12月18日 · Late Eocene opening of an ocean gateway between Australia and Antarctica was conjectured to have disrupted the EAC, cooled Antarctica, and allowed ice sheets to …

2022年1月1日 · The Eocene-Oligocene boundary is a divide of this history when the ice-free ‘greenhouse world’ transitioned to the ‘icehouse’ with the glaciation of Antarctica. Prior to this, …

2014年7月30日 · We find that growth of the Antarctic ice sheet caused enhanced northward transport of Antarctic intermediate water and invigorated the formation of Antarctic bottom …

2008年4月24日 · Explanations for Antarctic glaciation at the Eocene/Oligocene boundary fall into two main categories: those invoking changes in ocean circulation through tectonic opening of …
